rapidxml for D has been ported.

[zoujiaqing]

RapidXml is an attempt to create the fastest XML parser possible, 
while retaining useability, portability and reasonable W3C 
compatibility. It is an in-situ parser written in modern C++, 
with parsing speed approaching that of strlen function executed 
on the same data. RapidXml has been around since 2006, and is 
being used by lots of people.

Example:
```D
import rapidxml;

import stdio;

void main()
{
     auto doc = new xml_document;

     string doc_text = "<single-element/>";

     doc.parse!(0)(doc_text);

     auto node = doc.first_node();

     writeln(node.m_name);

     doc.validate();
}
```
